In the industry, packaging machines are essential equipment that enable the packaging of products into various types of containers. These machines are used across a wide range of sectors, such as food, pharmaceuticals, chemicals, cosmetics, among others. There are various types of packaging machines, each designed to meet specific requirements regarding capacity, speed, product type, and packaging format. Below, I will explain the most common types of packaging machines and their functions:
These machines are designed for packaging liquid or semi-liquid products, such as water, juices, oils, dairy products, cosmetics, or liquid pharmaceuticals. The type of container can vary, ranging from bottles, jars, to sachets or bags.
Common types:
Volumetric filling machines: These measure the volume of the product to ensure an accurate amount in each container. They are commonly used for low-viscosity liquids.
Weighing filling machines: These use a scale to weigh the liquid or semi-liquid before packaging, ensuring accuracy in the filling process.
Pressure filling machines: These use pressure to efficiently fill the container. They are commonly used for packaging gaseous or high-viscosity products.
Function: Fill the container with the liquid, while maintaining accuracy and preventing spills or overfilling.
Solid filling machines are used to package products such as cereals, biscuits, powders, solid pharmaceuticals, etc. These systems vary depending on the type of product (grains, powders, tablets, etc.) and the type of container (bags, boxes, jars).
Common types:
Bag filling machines (form-fill-seal): These machines create bags from a roll of film, fill them with the solid product, and then seal the bags. They are commonly used for products such as cereals, sugar, flour, etc.
Box or container filling machines: These systems fill rigid containers such as cardboard boxes or plastic containers with solid products.
Sachet filling machines: These are used to package products in small quantities, such as condiments, capsules, or medications.
Function:: Ensure the proper and safe filling of solid products into their respective containers, ensuring accurate dosing.
These vacuum packing machines are essential for products that require a long shelf life, such as food or pharmaceutical products. The vacuum process removes the air from the container, preventing oxidation and the growth of microorganisms, helping to preserve the freshness and quality of the product.
Common types:
Vacuum chamber filling machines: The container is placed inside a chamber where the air is extracted before sealing the package.
Continuous band vacuum machines: These operate using a conveyor belt that moves the products through the machine, where the air is extracted and then the container is sealed.
Function: Remove the air from the container, creating a vacuum that helps preserve the product and extend its shelf life.
Modified Atmosphere Packaging (MAP) is a technology that involves replacing the air in the packaging with a mixture of specific gases, such as nitrogen and carbon dioxide, to extend the shelf life of products, especially in the food industry.
Common types:
Controlled atmosphere packaging machines: These machines modify the atmosphere inside the container before sealing it, typically using a mixture of gases.
Flow wrapping machines: Similar to bag packaging, but with a system that allows the atmosphere inside the pouch or package to be modified.
Function: Modify the atmosphere inside the container to improve the preservation of the product, especially for fresh foods or delicate products.
Flow Pack type packaging machines can be either horizontal or vertical. These machines are commonly used for products such as biscuits, cereal bars, chocolates, and others.
Common types:
Horizontal packaging machines: The product is placed horizontally in the machine, and the film is sealed around the product.
Vertical packaging machines: The product is placed vertically, and the film is sealed around the product.
Function: They provide fast and efficient sealing of the package, creating an airtight protection for products that require quick and functional packaging.
This type of machine is used for products that require the creation of the package, filling, and sealing all in one step. These packaging machines are very common in the packaging of liquids, powders, and solid products in bags or sachets.
Common types:
Form-fill-seal for liquids and powders: These are used to package liquids or powders in bags or sachets.
Form-fill-seal for solids: These are used to package solid products such as grains, sugar, etc., in bags.
Function: Create the package from a film, fill it with the product, and seal it automatically in a single process.
Packaging machines are vital tools to ensure that products reach the consumer in optimal conditions. From liquids to solids, packaging machines are designed to adapt to the specific needs of each product type, ensuring safety, efficiency, and quality throughout the process. With the advancement of automation and technology, the packaging sector continues to evolve, offering increasingly efficient and adaptable solutions.
